this morning's weird dream

There was a lost soul.  She was traveling back and forth through time trying to do something.  She was getting thwarted and losing the will to live.  She had the body of a doll and her face was a white mask.  She was floating in a lake and I thought she might drown.  I was trying to help her but didn't know how.  I couldn't understand what she needed.  I carved a rectangle into a white wall, trying to help her.  I waited to see if a small worm would write something on the wall--it didn't.  I thought she would probably die.
